RR L322 3.6tdv8 auto 2007 engine system fault

Hi as I'm new to this apologies if this is posted in wrong place, thanks in advance for any help or ideas. Got two new oem turbos and intercooler fitted by LR specialist two weeks ago. Had nothing but trouble since car is now rough running with a slight misfire especially on cold with smoke from exhaust and engine system fault on dash. I will attach fault codes. Any help would be greatly appreciated as prior to turbo fix it was all good and garage trying to tell me it's nothing to do with that repair and suggesting all sorts but don't want to keep throwing money into mid air. They have mentioned injector problem but I've heard this is both a big job and expensive

There was a fault like this posted a little while ago.
The first fault is the MAF sensor the others I don't know, your car is too modern for me, but they would suggest that your specialist has screwed something up. Sounds like the specialist does not know what he's doing, you need to take it to a Land rover dealer if you cannot DIY and be prepared for a big bill.

Yes exactly what I thought already paid out £4K !! Thanks for your reply

As I said, take it to a Land Rover dealer and inform your specialist that the bill will be heading his way as a result of his incompetence.

I will let them know, it's unfortunate as they've done work for me for many years on previous range rovers and their work has always been bang on and I trusted them.

The trouble is that the new stuff is so complicated that few understand how they work. With a main dealer you have more of a chance of legal comeback if things don't work out.
