Hi there, first post here.

My turbo seems to hiss very loud when i reach 3rd gear (like a noisy hairdrier!) and onwards and it seems to pull away very slowly, its not as noisy in 1st and 2nd gear and seems to pull away normally in these gears. It sounds like the turbo is working fine but there must be a major leak somewhere but as this is my first turbo diesel, and i have only had the car 2 weeks, i havent got a clue where to look or what to look for under the bonnet! (Dont even know where the turbo is!) Please can somebody explain to me what to look for and where to look as i have read most posts about turbo problems on all sorts of forums but im lost when it comes to measuring resistance of sensors etc like it suggests in other posts! Also, i only seem to get around 40 MPG, even on the motorway. Could the turbo fault be the cause to me using more fuel as the official figures say i should achieve in excess of 50?

My only other gripe with the car is the display panel that sits on the dash in the centre of the car. I believe this is the display that shows any faults / trip meter / clock etc? The problem is that it doesn`t work. Is there a fuse for this somewhere else other than the internal fusebox as all the fuses seem to be fine? If not, would i need a new display unit or could it be a wiring fault as it has had a new radio fit by the previous owner (was wondering if it was in any way linked to the wiring of the factory fit radio?)

Thanks in advance to anybody who can help me out, sorry about the long post!

Hi

Car is a Rover 25 with approx 50k miles on it.Car has developed a misfire in every gear completely at random intervals. It is a friend's car.I had a quick look as I have a limited knowledge and found a hole in the centre section.I patched this with aluminium tape as a temp measure.I also replaced 3 of the spark plugs.Spark plug no.3 (2nd from right under coil pack) gave me a problem and I had to admit defeat. The rubber head of the lead remained around the plug and the rest of the lead came away.Plug no.4 (RHS) had oil around thread and electrode.

The car was put into a local garage today and they have said the head gasket needs replaced. There are a load of questions that I do not have the answers to overheating,milky oil etc but could a head gasket failure cause misfiring?

Should anything else be replaced at the same time? Read more

I have been suffering a severe loss of power when accellerating, & have also noticed a sound like a blowing exhaust when the revs hit 3500, but also this is the point when i started to get better accelleration, but still nothing like it should be. The engine runs very lumpy when idling, & does not start as soon as i turn the key.

To add a twist to all this, i was attempting to accellerate down the slip-road of the motorway the other day, & just as i joined the carriage-way hitting 3500 revs it felt like i had just had a rocket shoved up my butt, & the thing took-off like a scalded mule, & seems to running close to normal at the moment, albeit still idling lumpy.

My garage said it was the EGR Valve that needs replacing, curious as it is a petrol engine, Ford say it could be the TPS, Potentiometer, or Air Charge Sensor.
Has any one got any ideas. The car is seviced every 12 months, so all the usuall bits like plugs, leads, filters, etc are ok. Read more

Hi,

I nearly decided to trade in my Volvo S60 2Ltr, and going for a Tdi. I have found a nice A4 2.5tdi. I have been searching he internet, and there is not much reference to this car, pleanty on the Quatro but not the 2WD version.

I know this engine is used across the range, and how people find this engine compared to the 1.9tdi, and how would they compare it.

Or is it better to save a bit more and go 4 the BMW 330D

Many thanks
