I bought back my old mk5
JoshB:
That’s awesome work to be fair, and what a legend your mechanic is letting you use his garage!
I’d have been tempted with some new driveshafts though, that rust on them looks out of place now…!

Time for a depressing update.
Always wondered why the check engine light didn’t show when the ignition is on. I sort of forgot about it but then I mentioned it to the guys who tuned the car, and they reckoned someone had covered it up. I feared the worst, but surely nobody would actually do that?? Well it turns out, yes they do, the previous owner is officially a c**t.
The car had a bunch of misfire fault codes when i first gave it a once over after buying it, which I cleared. And since there was no check engine light, I never thought about the codes ever again. Also, I’ve changed all the spark plugs, coil packs and the cars had a full service.
Well I decided to take the speedo out to see if I could find why the light wasn’t coming on. I can’t believe what I found!
As you can see from the pictures. After removing the tape, the check engine was on!!
Codes are the same as when I first bought it. P0300 - 0304.
Also when the plugs where changed, the plug in cylinder 1 was badly corroded and it looked liked water had got inside.
This led me to wonder if it was the head gasket. So I bought a test kit from Amazon.
If the blue liquid turns yellow, I’m in trouble. And guess what….
So now the car is going to the mechanics on Monday for a full diagnosis. He says he would be surprised to see a gasket go on one of these engines. But the test I used has good reviews, and it would explain the corroded plug. Plus, why would someone go through all the trouble of covering up the engine light unless it was a big job to fix.
Gutted.

I've never come across a head gasket going on these, it's super rare. Do you have the infamous generic milky oil cap by any chance?
But yeah, who ever taped that up is a right see you next Tuesday.

Nope, no milky oil cap. Though the oil consumption is a lot. I guess I’ll know more once the mechanic does his diagnosis.

That is really is $hitty news - it may have only blown into a waterway and not got to the oil.
A minor win - at least they only taped over the LED, I have seen older cars where the bulb had been smashed.
Where was it last MOT'd - they are meant to actively check for both CEL and ABS lights coming on with ignition.
