ADVICE NEEDED - MIS-FIRING ENGINE - MAIN DEALER AD

Background

I own an October 2004 (54) 997 C2 Tiptronic.

I have owned the car since October 2007 and have done 2200 miles since then.

The car is kept outside and not garaged.

The previous owner purchased the vehicle from Porsche Nottingham in March 2007 with 12 months extended warranty. This warranty expired in March 2008. The mileage then was 16000 (March 2007).

The car has done 4900 miles since March 2007.

The car has done 20900 miles in total and is serviced up to date. It has always been maintained throught the main Porsche dealer network.

So, as they say 'it's a proper car'.

The problem

The car has not been used much in the last 6 weeks - maybe 250 miles in total.

Today whilst driving the car the engine management light appeared on the dash display.

The car started to mis-fire especially when stationary.

I limped the car to my local Main Porsche Dealer - OPC (on their recommendation).

To my shock they have advised that the engine needs to be taken out to fully assess the damage !!

Cost 11 hours at £110 plus vat labour only !!

They have advised that they have changed the ignition sensor.

They have diagnosed the following problems:

1. Cam shaft Position on Bank 1 - Timing.
2. Multiple misfires.

Having taken independent advise I notified Porsche that I would get the vehicle recovered and take additional advise. I also mentioned that I am a member of the Porsche Owners Club.

Porsche then advised me that it may not be necessary to take the engine out !! and they would borrow a camshaft solenoid from a spare engine. This may solve the problem.

I have instructed them to proceed with this test.

QUESTIONS:

1. Has anyone experienced this problem , and if so how was it fixed , at what cost?

2. The Porsche dealership advised me that the engine would need to come out but when I advised that I was taking additional advise they changed their mind !! Thoughts?

3. The car is just 3 months out of warranty. With a car of this age & mileage should Porsche consider a goodwill payment?

Any thoughts or ideas would be most welcomed.

Many Thanks.
