HI - would appreciate some views or help.

I purchased an 07 Continental GT in August and was/am very happy with it.

A dash light came on just after purchase.

I had this checked by an independent and the exhaust gas temp sensor was faulty. It had seized.

In removing it and seeking to replace the garage were unable to refit due to a broken screw thread. The initial quote of £2k for the work has increased to £7k as the engine now has to come out.

Has anyone experience of this or know a work around. Another independent has verified the problem and said the engine has to come out so this is a last - and desperate - appeal to see if this issue has been faced by any other members, or if there is another way of solving.... Thank you....

 

If the R and L bank are the same sensor ? ————- bit left of field , block up the hole in situ and splice the connector into the good side .
ECU will get a signal , question is will it be fooled ?
Gotta be worth a punt , against £7 K + .

 

Thank you John - I'll raise that with another tech who is having a 3rd look at it for me. Much appreciated.

 

Although very tight surely someone can get in there and re thread it.ive just done mine but only resoldered a new board into the connector end as usually that is the part that fails so no real need to remove the probe from the exhaust. I put some pics up on a previous thread Personally I feel there is someone out there that could re thread that . What side has stripped the threads surely not both sides

 

sent you PM. Let me know how it goes.

 

Thank you...

 

Just to say thanks to all for the helpful advice I've received.

Being new to Bentley GT ownership I've spent a lot of time in the last week scouring all the excellent information provided here and am sincerely grateful to have found this community.

As an update on my situation it looks as though the engine does have to come out ( unless there's a last ditch work-around found - in which case will share it if so), but at least I have now found an expert ( based in Kent, UK ) who'll do it at reasonable rates and my seller from whom I bought the car in August is sharing the cost. Work starts today !

I have another question but will post as a new thread to get some of your valuable thoughts on what else I can do at the same time by way of preventative maintenance/improvement. Thank you all again.

I've had some very good news today, which is - as suggested by some very helpful members, for which thanks - my mechanic has found an alternative to taking the engine out to replace the sensor. He solved the issue by engineering a clamp to fit the part into the place where the screw thread had failed.

Thanks all for the replies - which were all passed on to him. Invaluable!

If anyone else has this issue then I know of a man in Kent, UK who can help at a fraction of the cost of the engine out option.

Thanks again to all.

 

I have a 2012 GT and L and R sensors need to be replaced. My mechanic has told me he does not want to snap or break the sensors because then I would have to pull the engine. IF he feels the sensors will not come out, he will stop and tell me to pick up the car. I don't have $7k to pay for this. I read the threads so my question is what would happen IF I do not get the EGT sensors replaced and continue to drive the car, will I damage the engine even further.

 

You can hire a machine that wraps around the sensor and heats it up ensuring it removes fairly easily your mechanic should know this the same.machine is used to remove stubborn nuts and bolts etc

 

Hi. I had the same issue. In my case the first "specialist" garage I went to tried to remove the sensor ...and broke the thread in so doing - then tried to bill me for the engine out cost of replacement of the thread and sensor.

The car was undriveable at that point.

In desperation I spoke to a friend who has had a number of high end sports cars. He knew a small garage - with no prior knowledge of GT maintenance and repair - who would have a look at it. I had the car trucked over to them. They made a bracket to fit in the hole the previous garage had made in their botched attempts at the repair. They then fitted the new sensor into the bracket. Cost was a fraction of the engine out quote. Car has been fine since.

It would have been a lot easier if the sensor was removed without causing the damage - however even in that case it wasn't a lost cause once a competent indy with some engineering skills in the locker got to look at it

Good luck and it will be interesting to hear how you get on.......

ps in answer to your question I recall I spent a bit of time looking back over old posts and came to the conclusion it wasn't worth the risk of driving with a faulty sensor. All the best.

 

Hi Guy

Could you please PM me the place you used, I am based in Bexleyheath Kent and have the same issue with my EGT sensor.

Many thanks

 

bentley dealer first i think for these

 

Hi Guy,
I was most interested in your post. I bought a 2006 Bentley Continental GT privately and have had it for 7 weeks. During this time on two occasions a fault message appeared on my dash saying "Overheating..Check Manual" and it scared the hell out of me. The first time it occurred I pulled over, turned the engine off and put the car on a truck to a local Bentley mechanic. He checked out the car, cleared the error codes and said the fans were working fine and the engine did not appear to be overheating. The dash temp gauge said 89 deg. It always says 89 deg when the engine has a chance to warm up. The car was performing well. I took no notice until the other day when it happened again, same error message. This time I took it into the local Bentley dealer who diagnosed the problem as a faulty Exhaust Gas Temperature sensor. They are fixing it now and say it will cost about 4 hours labour plus sensor cost. I suspect the previous owner also saw this error message and it might have encouraged him to sell the vehicle as he may have thought it was something more serious. I'm happy it was not serious.
