16519 - oxygen (lambda) sensor B1 S1:heating circuit malfunction P0135- 35-00 - -

[cuprascott]

Getting the above error in my A4 1.8T Sport. Does it mean the lamda is goosed?

Im also getting no boost from the turbo but nothing other to suggest a problem. i did have N75 errors so replaced the valve and wiring to the valve which seemed to fix the n75 error but still no boost. Ive changed the dump valve as well. Dont think its the MAF cos there is airflow readings on vagcom????

Any ideas?

Help??

Any other codes mate?

Most likley its the lambda sensor, this could effect the boosting and pereformance of the car.

 

[big eck]

Which sensor came up tho mate???

There are 2 afaik one before and after the cat

I have just replaced the one on my cupra (pre cat) due to it failing and bringing on the EML but I didnt have any boost issues due to it failing tho

 

[Big_daddy]

B1:s1 is precat sensor

What Big Lad said, the one in the Down Pipe, and yeah.its fried, there crap, just about to put my 3rd in 2 years in as the EML is on again because of it. not really affecting perfrmance, just the fuel consumption, i have lost about 80 miles from a tank because of this. When the last one went, the car ran like a dog, stuttering, misfiring bad boost etc.

Wheres the best place to buy a lambda from?

 

[smoothuk]

Stick to the dealers mate, think (off the top of my head) was about 120-130 for the last one. Bout half hour tops to fit yourself.

No where else ?

I hate going to the Dealers, all ways feel like i'm getting ripped-off!

 

[Stan 24v]

Try a post on the MKIV's forum mate, Im sure someone will have one for sale.

 

[Stan 24v]

Ive done it for you mate, here is the response:

Evning mate

I am unsure if i have these, I can check for you tomorrow and get back to you if thats ok? Make me an offer on them and I have them we can negotiate a price Yes

I have the following bits from a leon if he needs them - front suspension, front crossmember, hubs, driveshafts and CVs. pas rack and a couple pipes.

Cheers for your interest,

Gervais

Let me know what you want to do via pm buddy.

Cheers Stan 24v, I appreciate u taking the time to post the request for me.

I've done some calling around myself and have found the GSF do it for £49, going on my engine code.

Think I’ll take the old one out first and check it, before I buy it.

id probably go OEM going on what guy told me today with a kit car....tried cutting corners bought an aftermarket sensor and it shorted out inside and nacked the ECU :S
