My mech has Vagcom and that is what was used to do the logging, not entirely sure what exactly was logged/checked.
Timing could be well worth a check so will put it to him to see what he reckons.

At the minute I deffo feel like selling the car for sure, i've put it on the Civic Type-R forum to see if anyone wants to swap for my derv.

I'm just thinking if my economy is out the window and has been for a while then I may aswell get something that goes as much as the fuel does if you get what I mean.

Car seems sluggish now on pick up and sometimes feels like the turbo doesn;t want to fully kick in, kinda like limp mode but then the turbo will kick in late.

I mapped out my EGR too, one of the first jobs I did after cleaning out the intake!

Have you easy access to VAGCOM, it's a very quick and easy check to see where your timing is :wink:

asif has a PD engine Rich, so that doesn't apply. imo the maf has gone kaboom!

Ah! Ok, yes you can't use it with the PD engine. Cheers Chris.

I think I read that the MAF has already been replaced.

Aye, I saw that the MAF had been replaced. At least that's what I thought it was safe to assume?

Hence my comment about the temp sensor. Would be worth getting a new one plumbed in anyhow.

Yeah the MAF was replaced approx 8-9 months ago.
What would bugger the MAF so quick? the previous MAF was in the car since atleast 30k for sure may have been the one from factory. So what would make my MAF go so quick in such a short space of time?

It was a brand new Bosch one aswell, don't really have the pennies anymore to just chuck one in for good measure to see if it sorts my problem out. Cuz like the intercooler i'd be in tears if I spend more money on parts and the car runs the same or worse.
I'd be fooking suicidal soon :grin:

I was talking about the temp sensor not the MAF. Sensor is usually around £10 ish.

Actually, just thinking about that, can you not still check it with VAGCOM? OK the graphs won't work but if you go into 01-Engine, Meas. Blocks-08 and select group 000 won't field #2 show you the fuel timing? Just curious :undecided:

In my experience the MAF should be good for 70K.

You can probably check that temp sensor in VAGCOM too, but as Slick says, for £10ish probably worth trying anyway.

For £10 I suppose it aint too bad.
Nothing has ever showed up on Vagcom for my car ever which does my nut in, cuz i'd love it if Vagcom could say this is where your problem is, just it and you'll be sorted :grin:
