Misfire after cambelt change on a4 3.0 petrol ASN

It's can be a tooth of or so have him check the timing again it's all the same 😆

He is probably one tooth off on the timing belt job. Takes a couple heat cycles for pressure in the coolant reservoir to even itself out. Pressure in the coolant system is normal. It is bad when you see air bubbles rising up through the coolant

You might have a bad water pump fins did you change the t-stat as well

[arvydasxx]

He did put a genuine cambelt kit with new water pump on, no i didnt change a t-stat on it, it seems that old one works fine, it gets up to temperature in couple minutes..
taking it back back to garage on wednesday,..

[arvydasxx]

Had it in garge and they say its a coil's, going to audi dealer for recall see if thats solves the problem..

[arvydasxx]

HI, just an update, its all sorted now, it was a timing slightly out..

[kkbatton]

Good to hear. Did he fix it for free?

[arvydasxx]

Yes it was free, did not fancy paying for job twice

So all going well got misfire again.
I was overtaking lorry and at around 6000rpm EML started flashing(I am sure it means a misfire), so now if I reach 6000rpm it always flashes, any ideas on that? it never misfires unless I push it hard up to 6000rpm..
I know I have bad sensor on exhaust, can it be related to misfire?

any ideas on this one? it only happens at that rpm range, otherwise will not misfire at all, if I drive gently she runs very smooth
