Ever since I got my 1.6vvt it vibrates when its hot quite heavily I can feel it in the seat and the steering wheel, plus it knocks for a second or so everytime i stop completely or change from d to r and vibration increases also when ac is on I only did 8500 km its brand new. Dealer told me its bad fuel even though I only use 92 octane from trusted stations. any ideas?

Hi guys 

So yesterday I drove from Norfolk to West Yorkshire ~150 miles and noticed that now my car is idling a bit odd, will idle fine then the revs drop a little & it almost chugs a bit, then goes back to normal and the car idles ok again, then the cycle starts again. It doesn't cut out and no warning light.

I thought it was just doing a regen but it did it yesterday afternoon, evening, and today both times I've driven it. Ive now done probably 40 miles with it like it (that I've noticed

Hi guys 

So last night the Mrs broke down in the Astra, it was idling lumpy and wouldn't Rev/would just cut out under load.

No EML, no codes, RAC came out and hit the EGR 3 times with the handle of a screw driver & she was on her way.. Still idling weird but driving fine.

It's occasionally idled funny ever since I purchased it but never had any other issues.

It's a 1.7 CDTI 125bhp with 115k on the clock. Up to date service wise etc, new fuel filter in last 5k.

I took the EGR off t

Had this problem for a while , it’s the 1.7 110 sports tourer .
Basically the revs move up and down at idle and vibrates , it’s like a weird heart beat but feels like it’s about to stall every time it drops
Anybody know why it does it , had full service couple month back but done it for ages
Many thanks

Hi, I've just bought my first diesel and it happens to be a GTC SRI 2 ltr CDTi. I love it. My only question so far is that when I initially start the engine from cold, it's not a smooth idle and you can feel it through the car with a slight rocking. Is this normal? A common problem? After a few minutes, it idles fine and there seems to be no other issues. I searched for the answer before posting so apologies if the answer is buried here somewhere.

Thanks.

I have a problem with high idle. I replaced the scv this weekend but still the same problem. It's not constant but sometimes idle goes to constant 1,200 even when engine is hot. If I switch car off and restart again it goes to high idle.


From some reasearch someone mentioned alternator problems could some shed some light on this problem please ?

Scv rotation position does it make a difference ?

Thanks

Hey guys,

Noticed something alittle odd on my 1.7 Astra GTC 62 plate.

I was letting the car idle stationary and was hold the revs at certain ranged.to get the engine warmed up.

I noticed when the rev counter hit approx 1500rpm - 2000rpm I could feelnthe car shaking abit, but then below or above the rev range it would smooth out and be completely normal?

Any ideas on what it could be?

Thanks in advance.

Hi all, my Astra J is hunting on idle and has various error codes being displayed. I thought the hunting might be the SCV but the fuel consumption at idle doesn't match the other posts on this issue:

Astra J Hunting

I have the SVS error message and these are the codes that were pulled:

P037E - Glow Plug Module Feedback Low Voltage
B1517 - Battery Voltage
U0164 - Lost Communication With HVAC

Then I have a list of Door, wiper, light and washer
