The old hesitation after remap problem

Lex Dysia · 31-10-2008, 14:16

Right having covered a couple of hundred miles I can say......It's an improvement but not a cure. Still getting odd stutters but not quite as bad. Now though the revs climb abit when I change so might try a weaker spring in the DV to cure this.
I have a Revo sps and reverted to stock map and car runs smooth as anything am back on performance map though as I prefer the power even with the stutter.
I have had a thought about this because I still am sure that I have heard what sounds similar to dv sound on part throttle accompanied by the momentary loss of boost and think maybe the problem is exhaust side specifically the turbo actuator.
I figure that increasing the boost may be to much for the old componant and like a dv with a weak spring bleeds boost this could be bleeding exhaust gas through the wastegate.
Had a look at this and was thinking of trying it with a slightly harder spring Forge Motorsport | Alloy Fabrication . Will contact forge and ask them if it fits first.

Today I got the engine light up and a scan revealed 16795 Secondary Air Injection System (B2) - Incorrect Flow
or Secondary Air Injection System: Incorrect Flow Detected : P0411
I am guessing this is a result of disconnecting the N249 so have cleared the code and will replumb everything in tomorrow

What you may have done is removed the vacuum line to the N112, which is the vacuum valve that opens the combi valve on the the head, to allow the secondary air pump to blow air in. That error code indicates that your secondary air system is not working, so i recon it's down to that valve, since it sits right next to the N249.

You should be able to get the secondary air working again. This picture should help you:

Lex Dysia · 03-11-2008, 10:57

Yes I figured it was the N112 as well anyway its back to normal plumbing now so I don't anticipate it coming on again.
While plumbing it back in though I did make an interesting find which seems to have smoothed things out lovely but time is the teller.
You know when you look and think something is different, spent a moment scratching my head and then thought my coilpacks looked wrong somehow, pressed down on one and it slid down about 7mm. They where all like it even the one under the vacuum cannister

don't know why as I changed the plugs myself back in March and know I pushed them firmly home.
Anyway so far so good but I will be monitoring them.

millie · 12-11-2008, 20:25

I had a remap and it hesatates and sometimes the remap dont work at all. Any suggestions

Lex Dysia · 12-11-2008, 20:42

What map is it?
Mine is smooth as silk now. The cure? Well a very simple one for me luckily. Coil packs had popped up, I pushed them in and next day they had lifted again. Closer inspection revealed my plugs had worked loose and leaking gas was blowing the coilpacks up causing a splutter as the boost came in on part throttle. Don't know if the loss of compression or the bad coil/plug connection or both combined caused the hesitation but I torqued the plugs up to correct values and the coil packs have not moved since. Now the car is running fine with more power, smooth acceleration and better mpg.

Lex Dysia · 13-11-2008, 17:14

Am currently trying Hitachi coilpack revision E, they are bolt down ones and they seem very good so far. Ordered them from vagproducts and recieved them today. No more pop up ever

They have received favourable reports on other forums for reliability so thought it was worth a punt

Nice one Lex Dysia, how much did you pay for them? Im thinking about getting some. Thanks.

So I cleaned the TB after all this, and now it runs good as gold! It's faultless now. I must have done about 5k miles since, and it's still fine. Smooth persistent power.

I've since fitted a boost gauge to monitor the inlet pressure, which should help me keep track of things. I've even trialled the APR stage 1 map, which hit a lovely 17psi peak, and things are still fine.

My advice would be to clean the TB before you spend any more cash on guesstimate solutions like I did.

Yep TB clean seems to of worked for me, so far so good! this is on a standard car, remap coming soon though.

Bodge · 14-11-2008, 16:58

My 17705 is back! After 6 months of freedom!

Looks like I'll be cleaning the TB again.

I guess it's just a standard service procedure now, to keep her sweet. Looks like the schedule is every 6 months.....

Now where did I put that can of carb cleaner?...

millie · 14-11-2008, 17:35

Ive got that fault code aswell. Maybe i should try cleaning the carb .ive had a smoke test and theres no leaks anywer

wat is tb?

Lex Dysia · 14-11-2008, 17:50

TB = Throttle body which is what you use carb cleaner on. There is NO carb on your car so don't bother looking for one

Here's a link to help you How to : Clean your throttle body - uk-mkivs

millie · 14-11-2008, 18:24

thats worth trying . mite save a lot of money to if it solves it. job for tomorow ha

Just a thought but have you ever taken the intercooler off to see what gunk was in it? I remembered this thread from a bit back http://briskoda.net/octavia-i/oil-sm...-worry/115628/

If the throttle body is getting dirty maybe it would be worth tracing it back a bit.
I'm taking mine off tomorrow to fit the FMIC, gonna be interesting to see what its like.

What do you mean by smoke test exactly, I ask because I can't see how that would prove theres no leaks. Unless it from inside the engine.

Nath_j · 14-11-2008, 20:38

Sorry abit of topic here but when cleaning the tb is it necessary to use a vagcom for the Throttle Body Alignment or will it run its self in ? just a bit unsure weather to do now or wait till i have a vagcom.

thats just a name for it,i dont think its actually smoke but it is some form of pressurised smoke. it goes in the engine and if u av a leak it seeps out . mine wasnt leaking.they cleaned my throttle body but ive still got the hesatating. the code p1297 is still popping up
