Nope they are not tied up, and yes you maybe right as I only have the CD model.

Removed multiplugs and that has erradicated the autobox fault (THANKU). One down lord knows how many more to go.

On starting up it now takes about 5 seconds for the EML to come on. Not checked O2 sensor yet. GOt to get jack out for that.

Did paperclip test again and its coming up with 0120 and 0340 so crank and cam sensor. Have already replaced the cam sensor and I know when autotune guy was here it did not show cranksensor as a fault cause he had engine running whilst doing test. Have found paperclip will only work when ignition is off!

Ahhh so we're making progress then! Presumably, when you removed the multiplugs, you then reseated them? ;)

I think you can only flash codes out of simtec ECUs (like yours) with ignition off

The 2.0, believe it or not, will run without a crank sensor. Make sure this is plugged in!!! will your car rev all the way up to the redline?

I still think something is unplugged or not seated right etc...

Have not checked the bottom end of the cranksensor as I cant find it. Ive found the top half and made sure that is connected however when I looked down the engine the cable disapears behing the air con unit and I cant see where.

What I have found is that the car sounds like its backfiring when you take your foot off the gas. Have not taken revs any higher than 4000 so dont know about that.

Can you access crank sensor from the underneath of car?? as I have a brand new one but didnt fit it as I could not find it!!

Crank sensor a bit of a bugger on the 2.0, but do-able. It's down by the passenger side engine mounting.

Plugs in near the injector rail...

PS, a faulty crank sensor, can also throw a cam sensor code... which may be happening in your case...

Just been out and tried to put it onto the ramps to check and found that its too low to the floor to use them lol

Will have to use jack & axle stand. Also reved her up whilst out there and found that she cuts out at 4000 revs and drops to idle.

When you say plugs in near injector rail, is that at the front of engine or rear as just noticed another connector the same at the rear?

Personally did if from above,

Most likely held in with an E8 torx bolt

If you've got a new crank sensor, I would recommend putting it in, to eliminate it.

Connector I think is near the front of injector rail (timing belt end)

Well Ive looked from above and had a feel(burning my arm) and cant see/feel it. I take it that it is mounted at the front around the air con compresor?

It's on the passenger side of the block, near the front....

Well I cant see or feel it from underneath so back to looking from above, however engine is a little warm at the momebt, its taking ages to cool due to it being so hot!!

Tracing the cable I would say that the sensor is roughly behind the air compresor but at the moment havent found it.

You are right about location - it IS a bugger on the ones with Aircon fitted...

It IS unlikely your CS would have failed, as a result of the work done, but if you're getting the code, and you have a new one, it can't hurt to try it!

Would you say it is easier to remove aircon unit or find it without touching it??

Dont want to have to pay for that recharging on top of everything else if  dont have too lol  ;D

You MAY be able to loosen the compressor and nudge it over enough to gain access, without disturbing the refrigerant

However, I would if I were you, await the thing to cool down, it makes things so much easier...

Maybe you could reach from below with it cold and get it...

I must confess to never having done one on a 2.0 with aircon!!!

Well I jacked it up in the air and there is 0 access to it, however i found by pushing the dipstick pipe over I could just get my hand in and guide the No 8 socket and medium extension on to it, but I cant get enough leverage to grip the bolt as I think Im slighlty at an angle.

Think Im going to have to either undue the compressor and nudge it over or remove the manifold which would give me loads of room.

Either way its a complete b###### to do when you have aircon. I bet its simple without.

Then to top it off I had the mechanic that did the intial repairs stood watching from accross the street making comments which really made me determind to sort this and say whose the mechanic!!!!!!!!

Tell him to bugger off... the only way to learn, is to get your hands dirty :y

I'd steer clear of manifold removal if you can...

What does Haynes say?
