Suggestion
Normally it's just the switch that goes, but because it is an obselete Porsche part, the OPC will replace the whole thing.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Hi guys, Just had new ignition switch and barrel replaced, what a bore. I am sure it is not related but from the very next day I get a loud screech (a couple of seconds) on firing the engine from cold along with acrid pong (and very occasionally when warm). Am presuming it's a belt. Does anybody have any knowledge/advice/experience of anything similar. Really don't want to spend another three hundred quid this month along with brownie points in equal measure in Valentine's day week..... All the best Des

POST 2Original post

It does sound like the V-belt. Get it seen to quickly before/in case it snaps as otherwise a lot of ancillaries will go (A/C, power steering/alternator etc) It's shouldn't be pricey at all.

POST 3Original post

Why the barrel? Normally it's just the switch that goes, but because it is an obselete Porsche part, the OPC will replace the whole thing. You can get the original switch from any VW/Audi dealer for about £20, and either do it yourself (instructions on the DIY pages) or get an indy to fit it for about 1/2 hours labour. Too late now, I know...... I agree with Rod - sounds like the polyvee belt. About £25 plus 1/2 hour (tops) to fit.

POST 4 / ORIGINAL POSTEROriginal post

Thanks, Richard. I had looked at your guide and found it beyond my modest tech skill in the time available. Jaz replaced it for me, apart from the switch the barrel had jammed and was out of true - it was virtually impossible to get the key out. Thanks to both of you for the belt advice. Who is the guy you refer to on occasion who is over this way Richard (I live just north of Maidenhead)? All the best Des.

POST 5Original post

I doubt if it was the barrel - the switch can cause that problem. Anyway, job done. My friend Tony Wright operates Wrightune in Wallingford, Oxon. <Link>
