Buying ABS module for HHC (hill assist)

[newskodadriver]

After seeing <mikeholroyd> today to try and activiate HHC (and XDS), I was dissappointed to find that my ABS unit was 1K0-907-379-BH and hill assist could not be activated (well you could, but you would just get errors). XDS could, but there was an error message for the power steering (and I think also one for ESP, before it was deactivated), so we decided to also leave XDS deactivated. I will ask at my MOT this week for the mechanic to check what exactly the power steering error is, as the car drives fine. 

 

Basically, I need to change the ABS unit to one of the variants so I can have both Hill Assist and XDS activated. I can't change the car now, and not rolling back on hills is a feature I consider essential. Having a (semi) automatic car that rolls back is positively medieval. I might as well buy a horse and carriage. 

 

When I search parts on ebay. I am very confused by the results that come back. Some are astounding expensive, about £700 (used with something like 30k miles). Some are considerably cheaper at say £200, or even £45 (no mileage, "tested as working"). Some pictures show a black block, then a white metal bit, then a round cylinder on top, some pictures just show a black box. Some say just say "ABS", some say "pump", others "ECU". A lot of the listings seems to have 2 lots of serials, one that starts 1k0907379**, and another one completely different ending in "517CP"). And many do not say Skoda, but Audi, or Leon or VW. Even when it says Skoda, it will say Yeti, or Octavia. Some mention the year, eg 2010.

 

I don't understand what it is that I am supposed to be replacing or what it looks like, or how much its supposed to cost (as I don't know if ABS is meant to be an expensive component or cheap) or if any of the above matters (like mileage?).

 

I have a Skoda Superb 2.0 CR170 DSG Diesel 2012 reg Elegance. 

 

Would appreciate any help on helping me buy a suitable used replacement. Or if you think that's a bad idea, point me to a new one. Thank you.

For what it's worth, I have HHC and XDS, and my ABS module is 1K0 907 379 BA in a Skoda Yeti 2009.

Glad you got sorted with a scan anyway.

 

Edi: In fact, the whole scan log of the ABS module might be of some help...

according to this thread, your ABS module shouldn't have it??? look at <BA>

[Rustynuts]

Most certainly do have it. I use it most days.

[Rustynuts]

In fact I've just realised something. Every time I go over a particularly severe bump I've been experiencing a loss of engine power and definitely noticeable slowing of the car. I put it down to just one of those things, but having been reading up on XDS and how it works it appears as though it might be the XDS sensing the unloading of the suspension, and reducing torque/applying brakes accordingly. Might have a play and turn it off, see if it improves things.

well i think i found a few that might be suitable. the abs unit seems to be a "block" of both ECU (black box) and pump (black cylinder).

 

basically. would you buy an ABS unit for £40. no other info other than "tested working ok"?

[Rustynuts]

I'm not sure.   It's not something I would like to say as it all depends on how truthful the seller is, and how much of a "test" the unit had been subjected to. Basically, I just think they all say "Tested and working" and wait for the buyer to come back and say it isn't okay.

Similar to this thread, thought I remembered something from a while ago. After going over a hump back bridge a momentary loss of power as the suspension unloads  http://www.briskoda.net/forums/topic/333043-momentary-loss-of-power-on-steep-downhill-roads/?hl=loss+power#entry4004773

Yep, I was looking for all sorts of reasons why it might be happening. I never thought it was something designed into the vehicle.

[langers2k]

Got an autoscan with the error code?

 

As you have a BH, I'd probably suggest a BJ rev as it's a similar age. Just make sure you have a copy of your ABS lcode from VCDS before doing the swap!

 

Looking at the list, it doesn't look complete. Mostly as a BA rev doesn't have any PR-UGx codes associated with it which would tie in with Rustynuts having XDS/HHC enabled.

The parts fit many of the VAG group cars so that is why you see listings for all different makes and models of cars.

The 2 serial numbers are 1 for the pump the 1K0614517** this is the bit that is round cylinder and alloy block and the other number 1K0907379BJ is the contoller module (electronics) that actually does the bit that you want. You buy them both together as 1 part.

what about this one? it's cheaper. 

 

i'm not really that knowledgeable about cars. do you reckon if you just randomly buy one, then it'd be alright? (basically, is an ABS unit subject to "high wear and tear"?"  where do these comes from anyway, insurance write offs?

what is a "PR-UGx" code?

[langers2k]

what is a "PR-UGx" code?

 

PR Codes are Production Codes for all of the installed equipment in the vehicle. This includes everything from the Powertrain details such as Engine and Transmission Codes to the color of the paint on the car. On the list posted earlier, it lists the PR codes for each module: http://www.briskoda.net/forums/topic/298368-hill-hold-control/?p=3551764

 

For ESP capable modules (PR-1AT) there are four different PR-UGx (where x is a number):

- PR-UG0 = Hill Hold Control (HHC) OR Comfort Driving Assist NOT installed

- PR-UG1 = Hill Hold Control (HHC) installed

- PR-UG3 = Comfort Driving Assist installed = XDS

- PR-UG4 = Hill Hold Control (HHC) & Comfort Driving Assist installed

 

For the BA rev module that Rustynuts has, there isn't a PR-UGx code listed which suggests the list isn't complete.

 

You want to find a module with PR-UG4 and I would suggest 1K0907379BJ

BJ because it's newer? in which case why not "BL"? sorry, just curious about these different revisions.

I've enabled HHC and XDS and wouldn't be without HHC. XDS doesn't present itself that obviously - maybe because I don't really "press on" as such.

Have you had a quote to fit the ABS unit?

er no. not going to the dealership garage until later this week. i'm just trying to scout out a part first. dunno how much they'll charge fitting it. but i absolutely need HHC, so it'll get done somewhere, eventually.

Where are you based?

Where are you based?

North East

North East

Benfield in Harrogate were very good a number of years ago. You'll defrost (FFS!) deffo need a specialist with the right equipment to set it up correctly, that's for sure.

Only that I've retrofitted a BJ rev and know it supports HHC, XDS, PLA 2.0 and two stage ESP defeat

 

The BL might be able to do all the above but I don't have first hand experience.

 

I think as of the BM rev the lcode was longer which caused trouble with the two stage ESP defeat although that may have been resolved.

 

Two stage ESP defeat is where pressing the traction control button disables traction control, but holding it for 2+ seconds will also disable ESP.

PLA 2.0 is park assist, it needs 12 sensors and some other supporting modules.

[DEL80Y]

Try to find a local VW/audi specialist which should be cheaper than the dealer and will be able to recode and maybe get you the correct part.

I have found dealer shy away from this kind of work...

There are a few in the north east with a quick search of google

Just to point out, the new module will need coding when fitted to the car.

 

The MK60EC1 modules have part of the car's VIN number encoded in to the lcode. When a used module is fitted, the lcode won't match the cars VIN and will immediately reset the coding to zeros...

 

You MUST make sure you have the original lcode from the currently fitted module saved somewhere! Please don't let a garage near your car until you have this lcode safe.

 

Mike should have it if he did an autoscan and can either add it to this thread or email it to you for your records

I'm surprised a 2012 Elegance doesn't have an ABS module that is HHC/XDS compatible.My 2012 has the BJ revision and supports both HHC and XDS; I've only bothered with XDS.

 

I also wonder if the difference between modules is purely firmware or if there are hardware differences? It might be that a reflash to later firmware would do this but I've no idea if the ABS modules are reflashable.

I was lucky enough to have a compatible ABS unit in our 2011 Elegance. I've found HHC to be really useful. Did you enable then defeat it? If not, you should try it.
