Seat Leon 1.6 2001 engine cut out

[Fizzy]

Hi

I'm wondering if someone can help me.
My Leon rather strangely cut out on me today while I was parking it
The car was rolling downhill so was in neutral - So I cant put it down to - "you just didnt give it enough gas"

Though before it did the rev counter started bouncing up and down like a yoyo and then cut out - It did start again however and was driveable

Does anyone have any ideas on what could have caused it?

Also on a rather general note, my car idles (ever since I bought it 18months ago) at 600rpm I thought this especially low for for my car as all the cars I have driven always idle at 900rpm (ish) Is this normal?

Haha i get the same mate, my idling is all over the place when the car is cold, it also loves to cut out when its cold. I need to book her in somewhere and get things checked over, there are a few threads on cleaning your throttle body with carb cleaner, that helped me for a few weeks.

Hi Jimski

Just came back from a quick drive - and it almost did it again!!
The weird thing is I put the car in reverse and gave it a little juice and off the rev counter went again!! So I quickly put it in first and gave it some and all seemed to clear?

This is very weird - The car is warm though!!

 

[Jimski]

My idle is all over the place whether the car is warm or not, but it wont cut out when its warm, it threatens to though!!

It is strange!!

had this problem after a while the engine light came on it going in the garage on tues for a throttle body clean and gasket replacement hopfully this will resolve the problem..

does ti cut out when you turn the steering wheel?? if so there is a sensor which monitors the revs for the power steering i had this problem with my car i jus disconnected it! amm the sensor is located at the bottom left hand side of the engine near enough exactly below your driver side light i disconnected mine and now she doesnt cut out when im trying to turn the wheel but still does the odd time when im driving so to say must be a common fault with the mk1 leon esp if you have the 1.6 8v like me haha

just had the same problem, kept cutting out when i dropped the clutch especially parking reversing coming to roundabouts, eventually the light came on it was the egr valve so i replaced thet and haven't had a problem since it cost £95 for the part from gsf and i fitted myself two 13mm bolts........
hope that helps

basically your best getting vag com done then before throwing parts on? mine was doing the same a few months back, i put new set of spark plugs and coil packs in her (needed the coil packs changed, done plugs during service) , its just started again with the same issues as you guys.

hi mate iv recently had this problem, get your throttle body cleaned and make sure u have ur throttle position reset and all the group values at the same time, any good mechanic can do this for u. make sure u have the group values and throttle position reset otherwise ur car will drive like a pig.

mine was doing my head in but now its driving like brand new again

well worth booking it in for this mate, hope this helps

i had a diagnostics done on my car and absolutely no faults came on the computer he said the only fing that it sounds like when im trying to start the car when she is warm and wont start is that there is like an automatic choke or sumthing stuck! il explain i dirve the car and she heats up to the runnin temp and i stop for watever reason and come back and the engine is still warm i have to hold the key in the starting position and let it wined and wined with my foot flat on the accelorator until she gradually slugishly sparks. also she likes to cut out the odd time like as described by the other lads lol i SAY SEAT F****N SORT IT FREE OF CHARGE HAHA

Best check the EGR Vavle (they carbon up very quickly!) Ive got a AZD 1.6 16v 2nd EGR now

Symptoms are

iratic idle
cut out
rev flat spots
Shite performance

May not show fault code mine did not untill i took battery totally off and did read on VAG COM then it showed!




Worth a shot!

 

[robbie2008]

cheers mate will do that are the parts expensive to replace????

 

[FASTER]

Not to much about £100 for the valve! do the battery trick see if it show fault codes first..

 

[robbie2008]

alright i take it to do the battery trick ya just simply disconnect a leg of the battery does it matter wat leg or if both legs of it need disconnected what order and will the car be ok when i reconnect it again wont need to do anyfing???? cheers

both teminals mate leave it for 5 min then reconect... Find your radio code first...

You will need to run the cars ecu learning mode with involves running the car at all rev ranges keeping around 4k revs i think, drop both front windows to the bottom and then top and run fans/aircon at fast speed so car feels a high voltage load under running conitions.... few oher small bits but can't remember what yet...

Get a mk4 golf manual (haynes) its in there!!!
