Hi Enes

the first time it happened all power was lost and by the time I had driven to hard shoulder and along about 300 yds the engine was sounding very rattly/noisy .

This time I stopped quicker and the noisy was just about to start.

But message did say power failure on dash ?
Customer: replied 2 years ago.

Yes Garage has just found out .It was a coil gone .Please can you refund the £15 as in this instance you were unable to help

Thanking you


Expert:  Enes replied 2 years ago.
I can't refund I only answer you paid the web page they process payment before you ask Question I only answer . What coil they replace ? Power failure message on screen dash is not from bad coil !
Customer: replied 2 years ago.

OMG is that right .They have replaced 5 coils , one of which was broke .do you not think this is the only problem ? Just collected car and driving home .Anita

Expert:  Enes replied 2 years ago.
5 coils can be bad they do to go bad they crack . And cause misfire and shaking and check engine light . But if you did see power failure message on dash that is most the time your alternator not charging or overcharging when it gets to hot and not supplying correct voltage now if voltage is off all system in car will be wrong . I think you will need new alternator if you keep seen again power service urgent message .you said orginaly you had coils pack replaced with turbo now you replace coils again ?
Customer: replied 2 years ago.

hi,they replced two of the coils to start.then atfer i broke down one had broken so i told them to replace all the remaining old ones.

Just drove home now it sounds ok but it does miss if i put my foot down hard for more power

Expert:  Enes replied 2 years ago.
If is still missing under load gas pedal pressed you got make sure they used correct coils ? And correct spark plugs Also alternator must be tested for good voltage charging
