Running lean on bank 1

Probably better to clean it in an ultrasonic cleaner like the four I bought in Aldi a few years ago for £15 each. I figured at that price it'd be handy to have a few spares for gifts to friends and in case one went wrong. Just the job for sorting out blocked injectors, dirty jewellery etc. I'm about to do my own lambda sensor before the next MOT is due so if you want I'll do yours too and post it back.

What was the car scanned with? If it wasn't VAG-COM/VCDS or a dealer computer I'd get it rescanned with one of those as they may reveal more info thana generic OBD-II scanner. If you ask on one of the VAG forums someone will usually do it for you for a pint or two.

Have a look here for suggested causes:

The best way to test a MAF is with VCDS, but a quick and dirty check is to unplug it. The car should run much worse.

It was scanned with a sealey VAG scanner I bought..

Thanks for the links. I'm going to give them a good read now.

Also been suggested it could be a VAC leak, and to open the bonet and have a listen for hissing sounds. First job of the morning :)

Then see where the MAF is located on the 1.6 16v 01 .. searches for haynes.

Ahh, that does sound a better idea and less crude. That is a very generous offer I may take you up on and will drop a few extra pennies in for a few pints *thumbs up*

I shall have a look for VAC leaks first and then remove the lambda :)

Forgot to mention a few months back a warning light came up on the dash engine management one, and I scanned it there and then ... well parked first lol ... and it gave a code out for a faulty lambda sensor. I erased it forgetting which sensor it was and waited to see if it came back which it didn't so assumed as was ok. Now within the last 12 months I changed the front pre cat lambda as it was faulty so I can only guess it was the other one, but possibly it could be the new one gone again ? (I do use mainly supermarket fuel, which I know is not the best grade)

But as I say no warning lights for the lambda came back. Just this new one about the engine running lean. Also worth mentioning I think is a slightly eggy stink but not noticeable now, or maybe I have gotten used to it. Well I do usesually drop the windows, perhaps not in this heavy rain were getting down south.

Thats about as much detailed information as I have to help.

Obviously you woulkdn't search for "Erwin Golf" or "bentley golf manual" Torrent as that would be bad.

No pennies needed. Someone on Usenet I've never met helped me out with some ram to upgrade my old pc and to balance my karma I need to do a favour for someone in return.

egg smell is often attributed to a dying cat

Yuk, a burning pussy !!
