Engine Problem - Misfire Cylinder 4, 5 and 6 - 997.2 (2010

Update.. I rang my local Porsche specialist (GCR Central) based in Leicester this morning they confirmed it was an hours labour which tied into to what demont said and also other DIY articles on forums. I then got a call back this afternoon saying the gen2 was more complicated then the gen1 and it would be 3 hours per side (6 hours labour £500+ in just labour + parts) total to fit two solenoids which is ridiculous. I tried to explain that the official Porsche book time to change the spark plugs (to gain acesss to the same area) is a lot less then 6 hours but GCR just didn't get the point. I must say disappointed with local independent Porsche specialist GCR Central.

For comparison I rang Porsche Centre Nottingham asked the cost to change the spark plugs for which they quoted £320 (supplied and fitted). When I asked them how much extra in labour to fit the same solenoids they said no extra in labour I just pay for the parts as they would have acesss to the area when changing the spark plugs. Just goes to show to shop around as in this case Porsche dealership is £200 cheaper then the specialist....

Lesson learned

I avoided OPC Leicester as they are probably the worst garage around. I've had 3 major bad experiences with them on my 911 and Cayenne where car has come back with more faults then when it went. Basics such as coding being done incorrect (coded my cayenne turbo as a manual which brought a error message and blamed the lpg conversion), bricking my PCM when it went for a map update, forgetting to reconnect sensor cables etc after work etc
 
I have to admit id forgotten how close the exhaust is on a gen 2 .. in my excuse ive been on the go for 14 hours when i post here :p

Its 1.5 hours to change the plugs so that sort of time to change the solinoid .. you only need to do the bank that the misfires are on .

You may well need to pay for an exhaust clamp as well .. its common that we cut them off to remove the silencer .

Best if i dont comment on the times you have been given .. bad form there .

Please point out to the garage the reason you want it done though , an extra half hours labour for them to be happy that this is likely to be the fault is worth it .

I cant see the car after all :)
 
Hi Demont, is the the exhaust clamp between the cat and silencer (see below link)

Yep thats the one .. if the bolts are too corroded to undo then we just cut it off and replace it .. which with our pretty poor weather and salty roads is done more often than not .
 
all fixed it turn out to be the solenoid. Ive replaced both sides , sparkplug and coil packs at the same time. was £135 labour + parts which is not bad. GCR Central (Indi Porsche specialist) wanted over £500 for labour. I will not be using them again...lesson learned :)

Hi there - can you confirm which solenoid it was please? I have what sounds like the same problem - my symptoms:

Starts ok
Settles back to idle -goes rough
If left to long, goes very rough at speed
If not left will run ok but Idle is terrible
Can be reset by ignition off / restart

Thanks
 
Dermot, once again you have gone out of your way to help a forum member, I have to say, that's bloody good of you & shows what a great chap you are.

Calibra, glad its sorted, I think you owe him a beer!

You need a fault code check to confirm you have a single bank set of misfires for this hi lift solinoid fault .

If you have a misfire on 1,2 and 3 then its Possible the hi lift solinoid has failed for THAT bank .

There can be other things which cause this fault so a code read out is required before just changing bits :)


@ cliffbase .. bless you .. just helping out though :)
 
Hi Demort- thanks for the reply - It will be going into an OPC this week to be checked.

Appreciate the information

Pete
 
Update:

OPC Solihull diagnosed solenoid on 4,5 and 6 - changed for a very modest fee, and she is now singing again.

Lovely Jubbly!
