Help Needed - Emissions

justtheonce

Hi

I am already a long time user - but have somehow logged out and can't remember password..

My car is not used on a regular basis, and on occasion I have had to have the car jump started as the battery had died.

Last time this happened, the check engine light came on, so a trip to the garage for a repair, service and MOT.

They did service, and repair, but, the light was still on, and not showing a fault when they did diagnostic, they then said that they didn't do MOT's at that particular site.

I took the car today to another branch, and the car failed MOT on the emissions. They did not appear interested that I had just been charged 230 for a repair that was supposed to have rectified it.

I am going to phone original branch in the morning, what should I be asking them to do.

I don't want to pay another couple hundred to fix something I thought was fixed.

I have read on various forums that people have driven their cars for years with this light showing, and I would too, but I think since January it's an automatic fail for MOT.

Thanks in advance for any and all suggestions.

The repair probably did rectify the eml fault light. The emissions are high due to low use. Give it a decent run with a bit of boot and probably some redex or similar and problem goes away.

If its petrol, put a bottle of cataclean in it, take it for a run for half hour at high revs just before mot test (eg 50 mph in 3rd gear)

and get the light extuingished, it is a fail, but if it comes back on 4 days later it doesn't matter

Thanks.
I did put cataclean in, as suggested by first branch when light didn't go off, and have been using it daily since repair.
Should original branch investigate and repair?

Always serviced, and this is 1st MOT fail.

Yes, and you most likely have an exhaust leak which is making the lambda high.

Looked at the receipt from original repair and it states bank 1 lambda changed, so, should original depot fix this?

No, you have a 2nd issue which affects the emissions test.

And when they fix that you may have another repair that fixes the emissions.

But without all 3 items fixed the emissions wont ever be right.
