Prius (Gen 3) :: ICE Off In B Mode Boost Regen


Dec 19, 2010

The other day I was driving down my street which is a decent grade (you have to curb your tires when parking) ... in normal drive mode at about 20mph with my foot off the accelerator pedal, I get about 10amps of charging as I coast down the hill. (I was in ECO mode, ICE fully warmed up)

For no reason I put the car into B without doing anything else and suddenly I'm getting about 25+ amps of regen. Going back to D instantly put it back to 10 amps.

I haven't explored this option fully, but it seems like the trick is to use B only once ICE is off under 43mph and you are slowing down. This will give you a nice regen boost (and slow you faster) without the brake lights being on. Just go back to D before you start driving again.

Up until this point I found B mode mostly useless.....

Passat (B6) :: Less Boost In Tip Mode?

Is there any difference in boost between drive and manually shifting with a tiptronic? How about using sport mode?

I saw a video of a guy testing hist mkv with apr stage two and he reported that he was not getting full boost when manually shifting his dsg.

Prius (Gen 3) :: HSI (CHG) Bar And Regen / Friction Braking?

Prius III -- I do all in-town driving with display in HSI mode. When braking, I have naively assumed that the length of the CHG bar corresponds with regen braking capacity -- fill the bar and you're starting to add friction brake. So when stopping distances permit, I try to brake gradually enough to keep a bit of space past the end of the CHG bar -- means I'm playing with brake pressure the whole length of a typical freeway exit ramp.

Prius (2010-12) :: No Regen Braking While HV Battery Overheats?

I had my scangauge installed at the end of Oct 2014 so I haven't had the chance to use it in the summer. I have also done the the Intelligent Power Module (IPM) recall about 2 months ago. I have never noticed this issue before the hot weather.

When the weather gets hot, the regen gradually lowers the recovery amp. Normally it can regen at over -90 amps. As weather gets hot, it limits the regen to about -65 amps max. When it gets hotter, the regen lowers down to -35 amps max. I can feel the car not slowing down as quick as at -90 plus amps. When the car has been sitting under the 100f+ for a couple of hours, regen is completely at idle (less than -20Amps.) Mechanical brakes take over. The car feels the same as -30amp regen, HSI shows it is regen braking. However, scangauge shows idle regen (less than -20Amp) and the slowing down is done by mechanical brakes.

Passat (B5) :: MBC / Limp Mode / Surging In 4th And 5th Gear Under Boost

I have a 2004 1.8T AWM auto tranny Passat with APR chip. CIA, Bolt down Coil Packs, Bosch F6DTC plugs, OEM cat to straight pipe to magnaflow muffler, N75J, Forge DV (not the 007).

I installed a MBC bypassing the N75 to keep the spike at 16psi and hold (the n75J i spike at 22psi and hold 12~14), When I did that, the car will go in limp mode from 'over boosting'. I have to turn the MBC down to 9 to keep the car limping out. I love the way the MBC have the boost curve (the N75 is too passive for me). would like to fix this issue.

Also, with the N75 and or MBC, while in the APR 93 oct chip mode, I always get surging in 4th and 5th gear. Any time the boost is over 10psi, it is like I have tons of boost, but the engine is not using it. APR said it is the tranny, the tranny shop said it is the engine or computer, the engine shop said it is the tuning.

GTI 337/20th Anniversary :: Boost Lost - Limp Mode?

Was driving the other day and one of the couplers came loos and I lost boost and went into limp mode. I pulled over, got it reattached, and after that it would only hit 10 lbs. i have a KO4-001 with the GIAC file and it usually hits 20+ and holds 20 lbs. I have a regular code reader and I had a code for the EBC, cleared it, rechecked the hoses, and verified with the flash loader that I was on the correct file, but it is still only hitting 10 lbs. What else I should check.

GTI 337/20th Anniversary :: Over Boost Codes / Limp Mode

There ended up being 6 or 7 codes. Originally the first O2 sensor and wire seemed to go bad, I replaced them and it ran well for a couple days and then started running like ass again...Now there are a few codes, none for the 02 sensor, but for over boost issues...Does this mean my n75J valve is causing the problems? Is it possible that my software is just going bad? ...I bought the car somewhat molested and don't quite know the extent of the parts on it, nor the brands( specifically, the software...).

The current codes being thrown:

P0238 mani pres g31 sig to high
P0234 overboost
P0106mani barometric sensor g31

We replaced the manifold pressure sensor, and am not having the issues but they could and probably will come back after 50 or so miles...Previous code also was P1114 02 sensors and we replaced the front sensor. It may be that the software that is on the car is starting to go..

Prius (2004-09) :: Ratchet Clank While Lightly Braking With Regen At 8 - 13 Mph

My 2007 with 58k on it started making the sound of a 'ratchet clankety clank' about at 56k while lightly braking with regen around 8-13 mph (slow and quiet enough to hear it best) and while turning slightly or more to the right. If I'm on a hill and can maintain the conditions, the sound will continue.

I've spent many a night searching here and elsewhere, learned a lot about strut and cv noises etc. At 57k I took it to a dealer who has a very nice service dept and they rode with me, agreed that they heard it, checked out the cv by hand (my first suspicion) and said all felt fine, that it was recorded at least (my concern being near 60k, std warranty).

Prius (2004-09) :: Regen Battery Charging / Working Extra Well But MPG Is Down

I've been noticing that my battery is almost always fully charged or close to it. Then I noticed that when I 'should' be getting assist from the MG2 and not charging the battery, i'm not getting the assist I would assume I should be getting. Seems like most of the energy is getting put back into the battery instead of assisting the MG2

Notice how the arrow is going to the battery from the MG2 (ELECMOTR) and not vice versa. This is majority of the time. Getting less of this also. hince - MPGs are down also.

Prius (2001-03) :: Loud Hum During Regen Breaking / Low Mpg - P3000 And P3009

Bought a used 2002 Prius in December of last year. When I got it home the hybrid system warning light and the check engine light came on, but after reading through priuschat for a few hours I thought to take a look at the engine air filter, which turned out to be utterly filthy. Replaced it and the car ran fantastically for the next 8 months, which was plenty of time for me to fall utterly in love with how quiet it is and how smooth a ride it is.

The carfax report for the car showed that its battery was replaced shortly before I bought it and that its transmission fluid was changed approximately 20k miles before that, so I thought (apparently mistakenly) that I didn't have to worry too much about either.

During these 8 months the car saw my regular mechanic for oil changes twice, had a bad CV axle replaced and I was told the serpentine belt was glazing and may need to be replaced with the next oil change, but neither I nor my regular mechanic noticed any other issues.

Prius (2010-12) :: Loss Of Regen Brakes And Traction Assist

Just letting Gen III drivers know that using an OBDII splitter and two gauges can sometimes cause a loss of regen braking and traction assist accompanied by various yellow lights on the dash. It can be restored by switching the vehicle off, unplug the OBDII splitter and restarting the car. This has happened to me on three seperate occasions.

GTI 337/20th Anniversary :: Sudden Low Boost - Soft Limp Mode?

Preliminary info:

APR 93 tune
Carbonio Intake
Silicone TIP

I picked up my 20th today and drove it 4 hours home. It has 74k on it, original timing belt. The timing belt kit is in the mail on its way here. Its the first thing I'm doing.

As I was driving it home on the autobahn doing about 150k/hr and I gave it half throttle to pass, I felt the turbo spool and I accelerated past the car. However, when I went to make the next pass, it felt like I had no power. I feathered the throttle a bit and it felt like my car was only getting maybe 3 PSI of boost. Very little actually. I do not have a boost gauge so I can't really say it accurately. As I was driving, i shut the ignition off and turned it back on. After that, I was able to get full pressure back.

Golf IV / Jetta IV :: When MAF Is Plugged In, Boost Cuts Out And Goes Into Limp Mode

I currently own a 2001 Jetta 1.8t. It is currently tuned for 15 psi supposedly. I have never seen that number been hit and the highest it will go(only in 4th and 5th gear) is 13-14psi on a good day. And even when it does get there it does not hold the boost what so ever. It will start losing boost almost as soon as it reaches those numbers. Another thing is my MAF is currently unplugged and is making my car throw a code. When MAF is plugged in it cuts out boost and goes into "limp" mode.

Here are some engine mods that may be apart of this issue:

- Front mount intercooler, full intercooler pipe kit
- Oem diverter valve
- N75 j valve
- ACHTUNING tune on 15 psi not sure which stage
- Forged turbo inlet pipe
- 032 motorsports crankcase breather hose conversion
- Ecs tuning
- 2.0t coilpacks and mounting plate
- AWP head

Prius (2004-09) :: Burning Smell On High Current Regen Braking

This morning I noticed a strong burning odor, like burning wax. It only seems to occur on high current regen events (eg coming off the freeway). It also happens to be raining, although I'm not sure if that's part of the issue or just a coincidence.

Prius (2010-12) :: Regen Braking Force Less At Higher Speeds At Over 45 MPH Or 70 KMPH

I have noticed recently that I seem to be getting less regen braking force than I used to. Particularly noticeable at higher speeds at over 45MPH or 70 KMPH. The regen seems to have very little effect now until I have slowed down. I seem to have to use much more brake than I remember recently. And by the way the battery in not nearly fully charged....Regen does come on but seems to have very little slowing power....
