Jerking during cold start from 1st to 2nd gear is a common problem for W221. It's a 7G gear glitch.
I have lived with it for 4 years already
Unless you do a transmission overhaul, nothing else will remove this problem even after Transmission ECU and valve body replacement.
To overcome this jerk, I simply warm up my engine for 4 to 5 mins in the morning, drive slow on 1st gear for a couple of meters while manually shift up to 2nd gear, there won't be any jerk after that.
Don't straight away step on accelerator hard on 1st gear, you will still encounter a jerk.
I had mine on for 2 yrs without any peeling. Went through petrol station car wash using powerjet washers regularly without any peeling.
Online search for other's experience seem like it last much longer. Especially if you are just using it on small parts like grills and chrome bits.
I haven't got a quote yet. but I assumed won't be more than 2.8K as the replacement of ECU + servicing of valve body is around that price. For your jerks, have you tried resetting the adaptive gear change (whatever it is called) - sometimes the gear changes jerk a little when I change driving styles :).
the base colours will be matt in look and texture.
You can add metallizer (which I did) or pearlizer coating for the additional effect you want.
Can add on a final coat of glossifier (which I did too) to get the smoother gloss look.
you can google those terms I highlighted in bold to see how they work and their effect.
The cool thing about plastidip is that it can easily DIY and if you muck it up or don't like the final effect (cos of newbie limited experience), you can always tear it out and redo it again.
I'll be getting a new E200 Avantgarde (W213) soon from PI. It will come with a diamond grill upgrade provided by the PI.
I'm interested to change to the classic grill, with a standing star emblem on the hood.
Can this be done on this model? If can, what is the cost including labour?
If it is possible to do a trade-in of the diamond grill, what is the trade-in price with labour?
Please PM me.
I would like to seek your advice between E200 AVG and E250 AVG. I know that E250 AVG comes with the widescreen command system. Basically, I don't really use those functions, for I only just listen to music and very importantly to have a good reverse parking and at times, the road map to locate a place. Would buying the E250 AVG is waste?
