As some of you may remember I had my 65k CLS remapped 3 or a4 weeks ago by a respected tuning company. I’ve been very happy, performance great economy ok.
Anyway got in this evening and car is holding on low gear and low revs, I’ve tried using Sport and steering wheel paddles but very slow reacting, also engine management light illuminated.
Now I’ve booked into my MB specialist in Cheltenham (who I trust) next Tuesday (soonest they can do). Should I take the car back to tuner first and see if they have upset something.
Any advice would be much appreciated

Best to leave it as it is so the Indy can have an uninterrupted, clean run at finding the issue. The more you start messing with it, the harder it could become for them.

The eml will give a clue . I'm going out on a limb and saying it's overboost at the MAP sensor .

You should really pull over , switch off and start again. Rather than driving with a car in limp home mode. 9 times out of 10 it resets itself till the next fault .

An engine light means a code has been generated - no one can advise on anything unless they know what the code is caused by the fault. It would just be the same as this

Thanks all for your input, as I said the car is booked in for Tuesday with Indi and they said it is ok to continue driving until then.
Does anyone have any views on this as it is my only car?

Just reset the ign when It goes limp . It should return full power , until it happens again, which will probably be the next time the turbo spools up.

I have tried turning off and restarting but to no avail. I guess I’ll just have to live with it until Tuesday I just hope I’m not doing any damage.

Must be something mechanical I'd assume then. Id not like having no boost tbh it can be dangerous in certain circumstances. At least your 4 way flashers will get a workout.

Safe mode is there to stop damage so I'd assume your ok to drive it.

Hmmh now I’m worried, my problem is I need a car over the next few days but only for say 10 miles at a time at max 40 mph.
Just wondering what would be the dangerous circumstances?

Overtaking usually or very steep hills . You're just gonna have to drive like miss daisy. Sounds like you've got that covered

UPDATE:
Just returned from my Indi, car sorted it was a split turbo lower boost hose, they also had to do a regen on the DPF as it was 270 somethings when 250 somethings would be a failure for an MOT. Anyway I’m so pleased it wasn’t something too serious or expensive and at last I can drive at a normal pace.
