Engine Clean

[Neel-Cupra]

Hi guys,


Im going to spend the day cleaning my engine bay tomorrow, does anyone have any advice on how to do this safely lol .. what do i need to cover up electrics wise? use cleaning products or a pressor washer

Just dont use an open hose.

When i done mine i started the engine so it warmed up a little, got my Megs wheel brush sprayed on Autoglym engine and machine cleaner left it for a minute and scrubbed like hell with the brush.

Used a pressure washer to wash it all off. Didnt cover anything and i've done this a few times.

 

[Neel-Cupra]

thanks phil, u sure none of the electrics need covering? just don't want to mess anything up, its a fairly high pressure washer ..

right got the engine clean done, drove to work and back, went out last night and the engine managment light has come on dont know whether its to do with the clean or something else, the car does drive and isn't behaving any different?

imo you shouldnt blast water into your engine bay. asking for trouble. maybe phil just got lucky each time he did his

 

[Neel-Cupra]

well i didnt take the engine cover off jus lightly done the strut area, coolant an the engine cover plus the side areas ..

 

[Neel-Cupra]

does anyone know what the light could be meaning?

 

[truCido]

could be a number of things mate...you need to plug vag-com in and get it checked out

This happened to mine after i was cleaning my engine bay, i didnt jet wash it but cleaned it by hand with a brush and cloth. plugged it in at work and it came up the coolant sensor. cleaned the plug up and moved the wires around then cleared the code and its been fine since. maybe just a bit of damp in the plug. try that mate just incase its the same.

I hope so, sounds like it would be a result if its just that, cheers mate, ill get it onto vag-com tomorrow morning ..

will be something thats really simple like any accessible plugs/senses etc... as know water would be able to get into the ECU and more than likely just dampened something somewhere!

Right had it on vag-com and it came up with 'lamba sensor behind catalytic convertor reached limit' is this down to the blueflame downpipe??? had it cleared and running fine so far ..

 

[nick-barnes07]

i would always steam clean the engine , jet washed my old car and it went tits up for a day or so

 

[Cupra_joeboy]

would of thought it was your down pipes fault, it prob just got wet and needs drying and re fitting.

 

[Neel-Cupra]

ok guys this fault code 'lamba sensor behind catalytic convertor reached limit' keeps coming up, including engine management light .. could it be a faulty cat? Someone help

 

[nick-barnes07]

steve gti 6 had the same problem with the sensor , think it was down to his blue flame system , have u got a sports cat

 

[Neel-Cupra]

yeah got the sports cat/downpipe on the group by not long ago, what did he do about it? what was it down to?
