Shaking took place first time last sunday.
I was doing 80km/h on 6th gear and dropped to 3rd quickly. I was going to pass this car ahead of me, but when i hit 3rd gear in the car started to shake and shiver like hell. Felt like car paralyzed in a sec. ESP didn´t flash even once.

Today i was driving 50km/h on 3rd gear when i accelerated heavily. Car started shaking again.

Both times i had same gear on, but different speed and revs. Not icy road etc.

This has happened only twice.
No any fault codes.
EGT sensors renewd 1 month ago.
Spark plugs and ignition coils 30 000km ago.

Has anyone else had similar issues?
What could it be??

30,000 on a set of spark plugs ..... Get them changed ....

What kind of plugs have you put on? partnumbers, brands & models?

see that thread, i bought the Bosch plugs. MRC will recomend the same, and they can be bought at the best price from Virdee. not sure how much your postage will be tho

One of your spark plugs is dead. Happened to me twice. Once it was just like 2000 kms after last spark plugs change.

30000km = ~18K miles

Plugs are now replaced with new ones.
There´s a second possible cause for this failure.

Broken joint. See pic.



Lil bit of welding tomorrow.

get them all welded up. no more boost leaks mate.

my weld had a pin hole size leak in it

yes i got the cam cover brackets done at the same time and they had some pin hole sized leaks so i mixed up some araldite and put it on the welds then heated it up with a heatgun so the araldite went thin and flowed. as i was holding it at the same time i could control where the glue went.

Aviation spec silicoset I use.
