When I had my car last week, stepping down on the gas would literally make the car feel a giant jolt

afer dealer changed the spark plugs and coil #2 ... car just kinda speeds up but feels like its not getting full power

so i reset the adaptive driving thing annd seems like i get a bit more power but still not all..


could they have f*cked up my hoses // vacuum lines when they were fixing the car?

 

take a trip back to the garage and voice your concern there you must be covered by their warranty on the work they carried out, plus you need to have it read for fault codes

 

im getting that giant jolt too... so ur saying changing the spark plugs fixed it? and how did u know to change coil #2, ive got vag-com how can i test the sparks? it started when i got the neuspeed chip which recommends different spark plus, but i heard sparks dont make much of a difference, so anyway how can i test this using vag?

 

if coil #2 has a fault VAG will tell you and the fault would be misfire, this is a madders question so out of my jurisdiction sort of but the plugs will make a difference but has to be done when its chipped so its hooked up to a computer and the results can be seen that the way it should be done

 

okay thanx, the part about coil #2 returning an error i understand, i take it my coils are fine as i have no error codes... however i dont understand what uve suggested about spark plugs sorry, so r u saying i can use vag-com to find out if sparks are good?

 

so r u saying i can use vag-com to find out if sparks are good?
not saying that exactly but you can log results while driving if your connected via laptop then you can compare results

 

sweet, who could tell me which block to log???

 

It would be easier to just replace your plugs with some NGK copper's at $2.00 per plug if you are unsure. At least take them out and make sure they arent toasted and are gapped correctly. It takes about 10 minutes.

 

the VAG software tell you what to do its called data log nothing to do with blocks

 

yeah i understandand its data log, but which data do i log... you can choose to log many things e.g you can log rpm, engine load etc... which one is for spark?
