A150 Intermittent start fault

[jrb1976]

My '06 A150 has developed an intermittent start fault. When I insert the key I hear it unlock the steering column with a shuffling noise but on turning the key there is just a click (although engine lights, radio etc all come on).
Sometimes if I remove the key and repeat process several times, it will start but at the weekend this simple strategy failed. If my journey is simply from A to B it will starts ok but if journey is A - B, B - C, C - D in other words after short journeys with multiple stops then i have a problem. On Saturday the car refused to start again after having driven 12 miles. After a 4 hour 'rest' it started first time. Obviously this is very disconcerting and potentially dangerous.

Using the spare key makes no difference - so I suspect it is a transponder/immobiliser problem. I am about to contact MB main dealer but browsing the forum, it seems other owners have experienced similar difficulties in the past. I would appreciate hearing from anyone who has any news, advice, recommendations etc - especially whether it might be a known Mercedes fault for which they acknowledge responsibility - i live in hope!

(BTW: The car is well serviced, low mileage 23500). Thank you.

if you are getting a click when trying to start it i would say it is more than likely the starter motor is on its way out, as if it were a immobiliser fault you wouldnt even get a click from the starter..

Welcome nursegeeza, interesting username. Unfortunately the OP hasnt posted since the initial post in April, so we dont know the outcome, but like Andy @ pcd posted, likely the starter motor is on its way out. Maybe you can let us know how you get on.

I have the same problem with my sprinter motorhome, main dealer has replaced the fuse board and relays, fitted a new ignition unit but the problem is still there. Dealer said 1st that starter motor was ok but I am beginning to think they have'nt a clue. So far I have spent over £1100 with no result.
