Misfire on cold start

[Tingle13]

I'm due a service in 400 miles so will need to do the plugs anyway

 

[BoostHard]

New MAF ordered from GSF £88 plus VAT gonna fit it tomorrow night

That seems steap!

I get genuine MAF's from dealer for £90.

EuroCar were doing them for about £60 but to be honest I wouldn't touch them.

Dealer only for me on these things.

Euros doing a Bosch unit for around £70

Prices do vary I know but not fussed over a few quid

mine doesnt miss fire per say, but when running at elevated rpm on a cold start theres a definate lumpiness in the idle, but as soon as the sai winds down and the revs drop she purrs like a kitten

possibly just one of the perks of the car?

100% Bosch



I did change my plugs with no luck.




Try the engine coolant temp sensor mate.

Changed the coolant temp sensor and thermostat I meant to add to that

Problem is they're reconditioned units and often aren't Better than genuine dealer ones.

Dealer MAF's are reconditioned as well.

 

[hyphon12]

Dealer MAF's are reconditioned as well.

Yeah but they're done by Bosch rather than an outside repairer.

 

[iSamKing]

Yeah but they're done by Bosch rather than an outside repairer.

Surely a Bosch recon is done by Bosch hence Bosch recon, and not some honkey tonk recon.

 

[Tingle13]

Changed the MAF tonight. Hopefully in the morning when the engines cold all is sorted !

Not necessarily, it just means its a Bosch MAF that's been reconditioned to Bosch specs, doesn't mean its done by Bosch. Just got to read the fine print on some, I know ECP ones are meant to be Bosch repaired, but it might just be a Bosch authorised repairer that does them.
Either way, I don't know why but when it comes to MAFs I've found dealer ones are always the ones to go for, not just for VAG cars but for the Mercs I work with and a load of other cars I've worked on.

Yeah, I agree. Dealer only for me, Just wanted to point out that the dealer ones are not new

Ah right, fair enough . Sod buying a brand new one, haha.

 

[Mo Arif]

I'm having this problem too, on a mk1 lc, everything has been changed

You tried cleaning the throttle body and do a reset on VAGCOM? I did so on my car a while ago whilst I was servicing it and it certainly smoothed out the throttle response.

 

[dazjstuart]

Mine did this for ages, When I serviced it I replaced the plugs and gave the throttle body a clean and a reset with vagcom, it hasn't done it since so one of those must have cured it. I would be tempted to say plugs as the throttle body wasn't really in need of a clean.
