Hi

My 2007 W211 E280 is playing up.

Twice now the ESP warning light has come on and I've lost engine power. I stop, turn off the ignition then start the car again and I can then drive off normally.

Now my scanner came up with lots of errors. I cleared them all except 2 - code 9028 and 930E (they don't clear).

Google tells me it could be a voltage problem. I replaced the battery about 2 years ago. Car has done 130,000km (around 80,800miles).

I did the trick to get battery voltage on the dash. Initially it read 12.2V, then went down to around 11V whilst cranking the engine, then up to 14V whilst idling.

So charging seems ok, Engine cranks over well. Any ideas as to what is happening?

 

Now I'm getting Low Tyre Pressure warnings. Tyres are in good condition (virtually new) and have around 40psi all round.

Google AI tells me that it could be the ABS wheel speed sensors. I replaced the brake pedal/light switch about 1.5 years ago.

Anyone? Someone? No-one? :-)
