I have recently started getting a slight humming noise on my 99 uk when starting her up. Its very slight but it kinda sounds like when i used to be on college holiday and trying to have a lay in and me mum starts hoovering downstairs

Any ideas what this could be? I also get the engine warning light on every so often and i sometimes on the dual carriageway get sudden fits as if power builds up then vroooooom it comes thru all at once, connected do you think or separate problems?

any advice is very much appreciated.

hey 2pac, West side.

Have you checked the ECU error codes ?

Dave

 

wouldnt have a clue how!!! have got it booked in for service on friday although he isnt a scooby specialist im wondering if he will know how to check.

Is it easy to do? it would have to be for me to do it

 

easy mate, get on your back and look up under the dash, as you sit in the car your left knee will be close to the connectors you are looking for, with your head under the dash locate the 2 black connectors and connect them (there wil be some green ones to but leave them for now) once connected turn the key to the on position and count the flashes.

first slow flashes then fast.

so 2 slow and 2 fast would be error code 22.

Code Faults :

11 Crankshaft position sensor

12 Starter switch

13 Camshaft position sensor

21 Engine coolant temperature sensor

22 Knock sensor

23 Mass air flow sensor

24 Idle air control solenoid

31 Throttle position sensor

32 Oxygen sensor

33 Vehicle speed sensor 2

35 Purge control solenoid valve

42 Idle switch

44 Wastegate control solenoid valve

45 Pressure sensor / Pressure exchange solenoid valve

51 Neutral position switch

 

excellent, i will give that a bash in the morning then.

does it repeat the flashes or do i have to be quick and count them first time?

 

be quick are turn key off and start again

 

It will keep repeating.

Its easy to count.
