When the launch of the WK diesel, even in relatively warm weather, the WK diesel engine should be checked, the candlelight module should be checked as it is quite often out of order. To change it:
- Order a new module. It will not only be original (number A6421532079) but also module from Mercedes with an OM642 engine-for example Beru 0522140202.
- I'm twit four bolts. If you roll bolt 4, you need to lower the nut to keep the nut down.
- We take off the old module, we put the new module back in, and we spin it back.
