Hi all, iv got an audi a4 1.6 AHL on 162k, and it seems to be using too much fuel (even more so than usual)

and recently, i have melted 2 spark plugs (one from number 3, another from number 1 so i doesnt seem to be cylinder specific)

im only a (very involved) hobby mechanic and was wondering if any techys out there would mind having a quick look through a vagscope log i saved recently and offering their opinions?

i have btw checked fuel pressure, which appears to be 3.5 bar


many thanks in advance

Steve

 

hello,

I also am the proud owner of an AHL engine 1999, with 162k also (km) . I have a similar problem but i fixed alot of it by spraying whatever electrical plugs i could find in engine bay, replace spark wires, cleaned the whole air intake system from filter to where it meets the spark plugs, air/fuel filter and 10-40W oil.

I`m planing to change the spark plugs with OEM standard copper ones, i`m using NGK iridium stuff now, dont like.

Another thing i`m suspecting is the O2 sensors, but i`m waiting for a VAG-com error, also the catalyst may be blocked.

I cant read those logs
Keep in touch...
