A question about DCC on an FR.

[serdar_18fr]

Hi all,

I just joined the forum and I already introduced myself in the new members section.
I made a quick search but couldn't find anything about my question, sorry if it's already discussed & answered.

We all know FRs have a lowered sports chassis compared to standard Leons.
What I want to know about my new FR with DCC is :

a. whether DCC-equipped FRs get the same lowering treatment or not,
b. whether there is any difference to the FR chassis, apart from the obvious adaptive shock absorbers, or not. Like different springs, bushes, stabilizers etc.

Thanks in advance,
Cheers,
Serdar

Hi and welcome :0)

The FR isn't lowered much, 15 or 20mm and I'm not convinced they are all lowered. We have a facelift FR ST and it doesn't look as low as some of the other cars I've seen.

Dynamic Chassis Control is always going to need special dampers as that's the bit it controls. It can probably apply the brakes as well but the springs are just bits of metal. My bet would be that the chassis is standard except for the adaptive dampers, as that's all you really need to change.

Thank you very much

Not that I wanted a much more lowered car or fiddle with factory-fitted suspension, 15-20 nm is already enough for me, if it's there of course
I'm just kinda a technical information freak and always wanted to know about all the details of the devices or vehicles I've been using.
I guess I need to look at some kind of parts catalog application where I can see the differences between trim levels & chassis types.
I'm coming from long years of Opel ownership and we had an app called EPC there, in which we can see every part using VIN numbers. I'm sure VAG brands also have something like that but as a newcomer I need time to adapt to the VAG world, I guess

Thanks for the response ?
and cheers from Istanbul.

If you look at the guides section pinned to to top of this page, the workshop manuals are there.

link is here:

General maintenance - Leon Mk3 Official Seat Workshop Manuals Link

Hi All! I obtained these a few months ago, and they've been a great use so far. Here's a link to all of the Seat Workshop manuals for the Leon Mk3 3dr/5dr. https://drive.google.com/drive/folders/1M4ofxxMgsFjE7hNWg6l4KuifelmdMUu0?usp=sharing...

www.seatcupra.net

If you look at the one titled ‘Running Gear, Axles and Steering’ you will find most of the info that you are after.

There is also a PR code sticker (in the owners manual / under the boot floor - albeit not always on newer cars) which will have all of the options fitted to the car, including suspension/running gear.

Thank you very much for the information, I'll be checking those guides out right away. ?

My PR code sticker was in the leather bag provided with the car along with owners manual and servicing/warranty booklets.
I hade already checked them from some source I found on the net

I think the PR code list on the label doesn't include all the features of the car.
I don't know which features (and why not all) they have put on the label but it should be much longer.

According to the sticker, my car has these PR codes:
--> I verified these ones against the link you've provided in your reply.
1AS = Electronic stabilization program (ESP)
1G9 = Space-saving spare wheel for temporary use radial tire (5-hole)
1NE = Wheel center cover
2B2 = Additional exterior noise suppression
2PF = Leather trimmed multi-function sports steering wheel
4A3 = Seat heater for front seats separately controlled
5RQ = Right exterior mirror: convex
5SJ = Left exterior mirror: convex
7MM = Emission standard EU6 plus
8GU = Alternator 140 A
8TB = Rear fog light
8WB = Front fog lights
8ZQ = Antenna for FM reception only diversity
9VD = Speaker (active)
B3D = Component parts set complying with vehicle type for Turkey various parts
C3S = Alloy wheels 7.5J x 18
D33 = 4-cyl. gasoline engine 1.4 l/92 kW 4V TFSI Base engine is TU0/TL1
G0K = 6-speed manual transmission
G16 = Front shock absorption
H7D = Tires 225/40 R18 92Y xl
I8E = Radio Standard (China)
J0S = Battery 320A (59Ah)
Q4H = Comfort sports seats front
QG1 = Service interval prolongation
X2F = National sales program Turkey
--> I had to look somewhere else for this last two:
V1L = Tire suppliers for sensitive countries
8IT = LED headlamps

There's no mention of Seat Sound by its name, but I guess it may be 9VD = Speaker (active).
Also no sign of DCC, but again it may be G16 = Front shock absorption.

Some of the other features of my car that weren't listed on the sticker are :

panoramic sunroof
digital instrument cluster
rain sensor
light sensor
4-door electric windows
foldable side mirrors
electric parking brake
auto-hold
cruise control
airbags
storage box under driver seat
headlamp washers
ambient lighting
rear reading lamps
rear usb ports
twin exhaust tips

There must be a more comprehensive list which can be accessed by VIN.
I'm going to ask about this to my local SEAT dealer next week.

Thanks again & cheers
Serdar

If you look at Section 44 (Geometry) of the workshop manual I referred to previously PR code G16 is referred to as ‘sports suspension’ and a 15mm drop front and rear versus standard suspension.

Yes, I saw that.

I also noticed that Cupra without DCC has the same ground clearance as FR sports suspension.
With DCC , it drops another 15 mm.

I infer from those tables that DCC makes no difference to the ground clearance on an FR.
They all have 15 mm lowered chassis, with or without DCC.

 

[black_sheep]

I would assume that is correct - think that the manual is dated June 2018, which was post FL model with DCC. I guess that you could always measure the ground clearance on your own vehicle in accordance with the measurement ‘a’ in the diagrams - I recall that it tells you what laden weight the vehicle must be to achieve.

Yes, I'm thinking of measuring to compare the actual ground clearance to the given data in the manual.

But it will never be a precise measurement because I wouldn't know where I should take the measurement exactly at the front and rear, also it isn't clear where exactly the measurement should start: At the lower end of bodywork, or some place at the underside of the car, possibly higher than the bodywork ?

By the way, manual refers the 'a' measurement as ride height, meaning the distance between the center of the wheel and the lower edge of the fender but it doesn't provide data for it. That would also be helpful for a comparison.

Cheers,

The measurement in the tables referred to as ‘Ground Clearance’ is the measurement ‘a’ referred to as ‘Ride Height’ in the diagram.

 

[serdar_18fr]

Oh, you are right, thanks for the clarification.
The use of two terms as "ground clearance" and "ride height" led me to think that they are two different things.
I should have known from the data (366 mm etc.) itself
