My wipers have an intermittent problem when, although they are working, they are not doing what they should be. When I push the stick upwards they should sweep across once. They might and they might not. They may stop half way across the screen. Same with other positions. May or may not do what they should. Also intermittent alarm fault message and ignition key in when it is not. When that happens it won't lock. Have to shove the key in the ignition and out again. It is never ending with this vehicle

My P38 has been very problematic in the time I have had it. Have paid a small fortune to various garages who treated me like I was a numpty. I searched forums to find answers to other problems I have encountered and printed out the info for the garages, but mostly they told me not to believe all I read on the internet. They were not the least bit interested in any info I gave them, but if they had been I would have saved quite a bit of money as they would not have kept replacing stuff that did not need replacing.
The latest problem included poor starting, which has now been solved and it now starts like new!!!! The ongoing issue is the response from the engine which is struggling to accelerate/ pick up speed. The garage thought it was the throttle pedal but then discounted it after using info I gave them. Having now come up against a brick wall after checking airflow, they are now going down that road again!!! Already the bill is £760 plus vat. Could do with some advice to solve this problem.
