Why would an oil and filter service kill me car????

Well, not strictly killed, but I've just come back from an oil service and power is way down - but I'm telling meself I must be imaginin' it!

Stage2 for years now, never any issues except for clutch slip which has been real bad recently.

But, turbo whistle is almost gone, even my clutch slip has gone - WTF????

It just seems to have lost boost?

1 They never said they'd flashed the ECU with updates, although I believe if they did the map would be unaffected anyhooz?
2 Has the greaser knocked summat?
3 Has the greaser broke summat?
4 Mental I know, but oil type has got nowt to do with it surely? (Just had full ester based oil put in)

Head's in bits :banghead:

Check to see if the knock sensor is still connected and the cable is intact. Its above the oil filter on the front of the engine below the inlet manifold.

Or get some decent pictures of the area for me.

Ignore that, you won't have it thats a sandwich plate with oil pressure and temp sensors in it. That picture was taken from above.

Its close as it is, the picture is decieving. Its very easy to damage the sensor or the cable removing the filter if you are a monkey.

Last time mine went to the main dealer RS specialist it came out with a damaged knock sensor, clowns. There were no visible signs of damage either, good job it was warranty as had the usual, "we need to do diagnostics, then you'll have to come back once we've got the part". How about you listen to me and just order one? Sorry we can't do that, blah, blah, blah.

Same symptoms as mine then mate? And what was damaged/how had they damaged it, if there were no visible signs as such?

Yep, same, no go. Had the code reader on it which found it and then had a cheeky run on the dyno to see the effects, only 200hp+200lb/ft and running very rich. Looked at the sensor and you couldn't see a thing! More than conincidence I thought, went in ok, came out poorly.

Got ya, so you changed it based on the reader and dyno finding it yeah?

I'm gonna take a look to see (hope) it's just dislodged or summat.

How long before you flagged it up to the dealer mate? I almost called them as soon as I got home but convinced meself I was just imagining it! Did they accept damage or just did it as a 'coincidental' warranty issue?

Yep, changed on the facts and data basically. Had it serviced in the morning, it didn't feel right on the way back so took a minor detour and slipped it on the dyno. Called the dealer as soon as i'd got the code reader plugged in on the dyno.

They paid no quibble under warranty, I was a very disappointed customer so they would have been paying either way!
